Especially when they look like artist José Naranja's.

Based in Spain, Naranja began illustrating his daily observations, ideas, and memories in 2015.

When he discovered the pocket-size 9x14 cm Moleskine notebooks, Naranja realized they were the perfect medium on which to transcribe all his experiences. He now binds his own notebooks, a process which he also chronicles in detail on his blog.

If you want to own one of his notebooks, Naranja sells a compilation of his best work in a multilingual book called The Orange Manuscript.

It costs €285 ($345) and comes numbered and signed. That price may sound steep, but remember that he binds each one, effectively self-publishing his own limited run of a super rare book. Check out his blog for more info on how to order your own copy.
